A fast-growing EV charging solutions provider required a compact, reliable AC/DC power supply to support advanced communication and control functions in their field-deployed charging stations. The team needed a robust, high-isolation solution that could deliver consistent, efficient performance under wide input conditions, temperature extremes, and frequent power cycling.
Key Design Goals:
Wide 85–305 VAC input range for global deployment flexibility
4,200 VAC reinforced isolation for enhanced safety
Compact size and high efficiency for space- and energy-constrained installations
Reliable operation from -40°C to +85°C for outdoor environments
To meet these requirements, the engineering team selected the MPM-30C series from MicroPower Direct. This 30W, compact AC/DC power supply offers up to 90% efficiency, robust EMI performance (EN 55032 Class B compliance), and built-in protection features including over-voltage, overload, and short-circuit protection. Its 4,200 VAC isolation ensures long-term safety and reliability for sensitive electronics, even in challenging field conditions.
By integrating the MPM-30C, the company enabled their next-gen charging stations to deliver reliable power—supporting the expansion of clean transportation with robust, field-proven solutions.
